The exact value of the cosine of 11π / 12 will be given as negatice (1 + √3)/(2√2).
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The trigonometric expression is given below.
⇒ cos (11π/12)
We know that 11π/12 is equal to 165 degrees. Then we have
cos 165° = cos (45° + 120°)
We know that
cos (A + B) = cos A cos B - sin A sin B
Then we have
cos (45° + 120°) = cos 45° cos 120° - sin 45° sin 120°
cos (45° + 120°) = 1/√2 x (- 1/2) - 1/√2 x √3/2
cos (45° + 120°) = - (1 + √3)/(2√2)

Describe in detail the most memorable visual aid you've ever seen used in a presentation. why does it stick out in your memory? how was it used to illustrate a point? what did you learn from this experience?
Answer:
Explanation:
The most memorable visual aid I have seen used was when a psychology professor used graphic descriptions (through historically important paintings) to illustrate abstract concepts, such as love, madness, and despair.
The representations used in the presentation stuck in my mind because of the visual impact that correlated with my personal experiences, making them vivid and memorable in my mind.
The points illustrated aimed at demonstrating the universality of human passions, and as such, it was an extremely successful presentation.
Finally, what I learned from this experience is that human emotions are not only universal, and as such, they can be represented, but, also, and most importantly, they are emotions that are not abstract concepts, rather, singular and personal experiences to which, paradoxically, everyone is subjected.
A certain market has both an express checkout line and a super-express checkout line. let x1 denote the number of customers in line at the express checkout at a particular time of day, and let x2 denote the number of customers in line at the superexpress checkout at the same time. suppose the joint pmf of x1 and x2 is as given in the accompanying table.
The problem here is a Joint Probability Distribution exercise. See the answers and explanation below.
What is Joint Probability Distribution?Joint Probability Distribution can be simply described as the likelihood of two events (variables) occurring at the same time.
These two events are commonly referred to as event A and event B, and their formal names are: p (A and B).
What is the solution to the questions?A - The likelihood that each line has exactly one customer: The probability relates to the associated row and column.
X₁ = 1 and X₂ = 1
P (X₁ = 1, X₂ =1) = 0.15
B - The sum of the diagonal elements of the joint pmf indicates the likelihood that the amount of clients in both lines is the same:
P(X₁ = X₂) =) p(0,0) + p (1,1) + p(2, 2) + p(3,3
= 0.08 + 0.15 + 0.10 + 0.07
= 0.4
Hence,
[tex]P(X_{1} = X_{2}) = 0.40[/tex]
C - Let A represent the situation in which there are at least two more clients than the other line: The following are examples of variable combinations:
X₂ =0 ; X₁ = 2,3, 4
X₂ =1 ; X₁ = 3, 4
X₂ =2 ; X₁ = 0, 4
X₂ =3 ; X₁ = 0, 1
The probability is thus computed as follows:
P (A) = p(1, 3) + p (2,2) + p(2, 3) + p(3,1) + p(3,2) + p(3,3) + p(4,0) + p(4,1) + p(4,2) + p(4,3)
= 0.04 + 0.10 +0.06 + 0.03 + 0.04+ 0.07 + 0.00 + 0.01 + 0.05 + 0.06
= 0.46
Hence [tex]P (A) = 0.46[/tex]

At the highest point, the speed will be the least. Then the correct option is A.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
A ball is hit at an angle of 30°.
Then the speed in the x-direction will not change with respect to time because acceleration is zero.
But the speed in the y-direction depends upon the acceleration due to gravity.
If the project an object with an angle, then as it goes upward direction the speed decreases and becomes zero at the highest point then it falls down with increasing speed.
At the highest point, the speed will be the least. Then the correct option is A.

A box shaped like a rectangular prism has a volume of 280 in^3
Based on the calculations, the width and height of this rectangular prism are 7 inches and 10 inches respectively.
How to calculate the volume of a rectangular prism?Mathematically, the volume of a rectangular prism can be calculated by using this formula:
V = L × W × H
Where:
L is the length.H is the height.W is the width.Given the following data:
Length = 4 in.
Width = (n + 2) in.
Height = (n + 5) in.
Substituting the given parameters into the formula, we have;
280 = 4 × (n + 2) × (n + 5)
280 = 4 × (n² + 7n + 10)
60 = n² + 7n + 10
n² + 7n - 60 = 0
(n - 5)(n + 12) = 0
Therefore, n = 5 or -12.
For the width, we have:
Width = n + 2
Width = 5 + 2
Width = 7 in.
For the height, we have:
Height = n + 5
Height = 5 + 5
Height = 10 in.

A box shaped like a rectangular prism has a volume of 280 in³. Its dimensions are 4 in. by (n + 2) in. by (n + 5) in. Find n.
The cross-sectional areas of a triangular prism and a right cylinder are congruent. the triangular prism has a height of 10 units, and the right cylinder has a height of 7 units. which conclusion can be made from the given information? the volume of the prism is half the volume of the cylinder. the volume of the prism is not equal to the volume of the cylinder. the volume of the prism is twice the volume of the cylinder. the volume of the prism is equal to the volume of the cylinder.
The volume of the right-angle prism and the right-cylinder shapes is not equal. Thus, option A is correct.
What is Volume?Volume is given as the scalar quantity that can measure the space occupied by a three-dimensional object.
The volume of the prism is given as:
Volume of prism = Area * Height
The volume of right cylinder is given as:
Volume of cylinder = Area * Height
The given two shapes are congruent to each other, thereby the area of the base of the prism and cylinder are equal. Substituting the height of both the shapes:
The volume of Prism = 10 Area
Volume of right cylinder = 7 Area
The ratio of the volume of both shapes gives:
Volume of Prism/ Volume of Cylinder = 10 Area/ 7 Area
Volume of Prism/ Volume of Cylinder = 1.42
Volume of Prism = 1.42 Volume of Cylinder
Thus, the volume of Prism is 1.42 times more than the volume of a cylinder. Hence, the volume of both shapes is not equal. Thus, option A is correct.
